There are strange numbers carved around the entrance to the upper part of the tower at Coral Castle. At both of the points marked in the image below are the numbers 7129 6105195. Edward Leedskalnin left these numbers here before he passed away.

These are engraved twice. Why? Perhaps Ed first did them lower down (2), and then realized that no one would see them. He may also have redone them higher up on the other side to associate and align them with other clues in the room.

Here they are:

These numbers have multiple meanings. Like everything at Coral Castle, there is a meaning for the public, and then a deeper esoteric meaning that can often be difficult to understand.

Rumors persist that these numbers are from a citizenship certificate Ed had. These rumors are quite valid! While visiting Coral Castle for myself, I was able to confirm and photograph evidence that these numbers, 7129 6105195 are the same ones shown on this certificate:

The petition number is 7129, and the certificate number is 6105195, the same as the numbers engraved on the wall.

This “certificate of naturalization” was issued to Ed in 1944, a long time after he had already been in the United States.

It appears as though Edward Leedskalnin was able to have some influence over the numbers he was issued, allowing him to integrate the numbers as another multifaceted clue at Coral Castle.

Many people will prefer at this point to believe that there is no other meaning to these numbers and that is understandable, though I would strongly encourage readers not to underestimate the greatness of the forces at work.

Update

The above sentences were quoted on page 72 in the new (and highly recommended) Coral Castle Book by Rusty McClure and Jack Heffron. And I re-quote from the book:

The site’s [Code 144's] director was not dissuaded from believing the formula significant even after he learned that the number was taken from Ed’s naturalization certificate. Given the passion and, in some cases, the erudition with which the proponents of what is called “ultrascience” state their beliefs, our goal is not to undermine or ridicule, but in this case, the ultrascientists clearly seem to be off base.

My response is that it is precisely this unwillingness to take a risk in one’s thinking that is why the great mysteries so rarely (or never) get solved.

The problem is that unless one is psychologically willing to take a risk of being wrong – to risk believing in something just for a while – one will never put one’s self in a position to see the next step along the way.

Because the very nature of coming to understand something is by progression. And you just aren’t going to see the next step, because you haven’t allowed yourself the perspective. You hold yourself back indefinitely.

It is only by risking enough in your thinking, you will come to have a chance of understanding how true these things are. And that takes inspiration - and a little faith that it might go somewhere, even if you can't see it right away.

I will not back down on the validity of these numbers and I refuse to subscribe to the parochial thinking that so quickly eliminates the interest of others. I confirm that I continue to have complete confidence in the meaning of these numbers, despite more waiting to be discovered, and that is all I will say on the matter.

In this case the steps have been carefully and strategically laid out by Leedskalnin, and like almost everything he leaves us, there are multiple meanings. These numbers have proved themselves to be a great place to start, and their relevance extends dramatically across the whole of the Coral Castle.

Breaking up the code

Many people recite the code as 7129/6105195, and assume a division sign in between the two sequences. I am not certain how this rumor started. In reality, there is no visible mathematical operator of any kind.

The first step to understanding the code is to divide it in the following way:

7

129

6

105 195

The 7 is seperated off from 7129, and the 6 from 6105195. Further, the 105195 are also broken into 105 and 195.

Ed’s flywheel has 24 V-shaped magnets arranged over 360°, meaning that each magnet takes up 15°, because 360 divided by 24 is equal to 15.

To help understand the solution, we need to look at numbers arranged over a circle.

The numbers 105 and 195 from the code above are angles and first define a right angle in this wheel. Notice that 105 and 195 are 90 apart (90°), they are also both intervals of 15 and thus fit perfectly into the values on the wheel!

Next, the 7 and 129 in the code can be solved with the sequence of adding prime numbers.The sequence of prime numbers added together need to also be added to our wheel alongside our 15° intervals.

129 is the sum of the first 10 prime numbers and this positions its value at 10 * 15°, or 150°.

This puts it at the center of the 105 – 195 right angle, at 150°.

Next, the line containing 6 and 105 195 can be solved with prime quadruplets and angles.

105 and 195 are at the centers of two consecutive prime quadruplets, what would be an amazing coincidence if this weren’t a code.

{101, 103, 105, 107, 109}, {191, 193, 195, 197, 199}

Incredibly, a ratio of Phi exists between the centers of these two prime quadruplets – created by the prime sequence positions of the centers of the two prime quadruplets.

For example, the prime sequence number of 103 is 27 because 103 is the 27th prime number – a prime sequence number is the position of a prime number in the sequence of all prime numbers.
The 7 and the 6

To solve the 7 and the 6, they must each be multiplied by the number of magnets on the wheel, 24.

This gives 168 in the 7 129 line, and 144 in the 6 105 195 line.

7

x 24 = 168

129

6

x 24 = 144

105 195

168, because it is derived from the line
7 129 which is related to adding prime numbers, also has its solution related to the sequence of adding prime numbers.

Indeed, we find that
168 is the sum of four prime numbers: 37 + 41 + 43 + 47 = 168, and these prime numbers which surround the 195° axis of the wheel, part of our right angle!

Further, 144 because it is from the line 6 105 195,
relates to prime quadruplets and angles.

There is a prime quadruplet that sits at prime sequence position 144, and another one at position 288.
